Thanks for the feedback!
I internationally made it a little difficult so a person would have to persistently train their game sense and develop a muscle memory as to what keys serve what purpose; although, this being a small game, I doubt anyone would go so far as to practise it.
I'm glad you liked the music and stuff. I tried my best to bring a feeling to the game which is authentic to the golden age of piracy and its great to see that worked.
Cheers!
